A Good advice by Gordon
If you want to become an expert programmer, google SOLID, buy GOF, buy POEAA, buy Clean Code, learn Refactoring, lookup GRASP, DDD, CQRS, DCI … but dont ask for PHP books. That's the most reasonable suggestion I can give you when you ask for Expert PHP books really.

I don't know how to star messages properly. I should be banned from the PHP room and Stack Overflow chat in general. I am a disgrace to myself, and my fellow PHP programmers.(:P:P and don't complain me LOL)

I am a website developer and a learning super freak. Recently I have been practising GRASP and SOLID.
